This invention relates to flat work ir'oners and particularly tothatclass including 'an ironing hed and one or more padded rollscooperating' with the bed.

Heretofore it has been customary in machines of this type to provide aniroi'iin bed having a plurality of curved4 ironing aces, formingtroughs, which receive the peripheries of pad ed ironing rolls mounted,in

suitable bearings guided in the frame and forced toward the hed by aplurality 4of springs arran be raised and` owered to bring the rollsllltQ and out of engagement with the bed. These'- machines heretoforehave been used for at-.

tending upwardly.

work of substantially one thickness and have i not been used with anydegreel of success: in ironing articles having buttons and of:` -unevenvthicknesses for the reason that the 20. pressure due to the weight ofthe rolls is sov great that the buttons are broken and good work is notproduced, especially in machines utilized in commercial laundries.

The present invention aims to overcome the disadvantages accompanyingthe use of these machines for general ironing purposes by providin meansfor suspending each ironing roll 1n a manner to cause, it to float, sothat each ironing roll will bear on thev U bedwith the necessary degreeof pressure to properly iron articles of varying thicknesses and leavethe buttons unharmed. The invenf tion'is also designed to reventunduefpackl in or hardening of le padding on the ro ls by reason of thefact that the rolls do not bear with unlimited pressure upon the ironingfaces of the bed.

Other 'features of the invention will be brought out more clearly inthefollowing description, drawings and claims.

Referring to the drawings, Fig.l 1 is a side elevation of the machine'with parts broken away; Fig. 2 is a section upon the line 2 2, Fig. 1*;Fi .-3 is an enlarged View partly in and Fig. 4 is a sectional view uponthe line 4 4, Fig. v3, some parts appearing in elevation.

Inthe arrangement shown inthe drawings, the frame comprises side members1,

'i each provided near its upper edge with roll bearing guides 2 as shownin Fig. 1. These fra-me members are securedtogether byany suitable'meansand by vthe hollow ironing ed in a member adapted to.

This is a struc-f ture which is common tomany-types of fiat work ironers. Mounted in the bearing guides 2 andsliding therein are roll'bearings 5 receiving the trunnions 6 of theironing rolls 7.". The `guides are usually inadewitlrgr V ings beintoward and from the'bed.'v Each of the .rol bearings is'providedwith anupwardly extendingfear-"S provided with' a slot 9 andpa spring ilot 10,the latter exe?l slot 9 receives a fpm' 11 passing through the sides ofa res` sure bar 12 extending theull length o the `machine and commontoall of therolls. En

pilot 10 is the' lower 75 pressure app 'yin .spring 13 having its upperend engaging e ilot on aresthrough Athe tov ofthe pressure b checknut'16 holds this screw, and 11e adjusting er pressure applying spljinany desired position.

`Each roll bearing yis provided downwardly extending spring pilgladapted to engage in the lower roll su po ing spring 18. Inithe caseofeach ro pressure spring 18 nests in a socket 19y yoke ineach si e ofthesocket 19 is pro with a air of ears 21 each receiving p 22 assin throughan eye .23v of a loiilergV spring ad]usting bolt 24. As above indig-jcated there are `two of .the adjustin bolts; thereof are threa ed andypass through lugs 25 forming a part-Iota;v racket or support 26. securedto a stationary machine part, such as the ironing bed, by means of bolts27. Each of the bolts 24 is provided .with a nutl 24 v to provideadjust- 10 0 ment of v.the lower springs, so that said springs ma be sopositioned relative tothe ironing be bythe supporting yokes 2() that theironing rolls 7 will just lcontact with ressure is being The pressurebars 12, one' on each side of the machine, are given their upward anddownward movement by'links 28."an d 29, each of which is provided withan eccentric is of a welljknown construction'. f Y 5 In adjusting -themachine the' pressure is strap 30 engaging eccentrics 31 arranged' ontransverse shafts 32. Each of these shafts is provided with a worm gearmeshing with worms'34 adapted to be driven by gear 35 which meshes with.a ranged on a hand wheel shaft 3g.. When the hand Wheel is rotatedtliepressure bars are raised and lowered to bring the rolls 7 into .andout of engagement with theironing bed.

This pressuremechanisni for the bars relieved from the upper springs 13and the lower springs a-re adjusted or positioned to carry the weight.of the rolls. The upper springs are then-adjusted tothe proper tensionto prod-ucothe desired ironing effect between the rolls, and the bedwithout creating suiiicient pressure "to break buttons on articlespassing through the machine. v

From the'foregoing it will be seen that the rolls float, as it were, inthe machine and exert the. proper eect Without any'undue pressure uponthe work, thereby preventing the breaking of buttons-and the unduehard;`

ening or packing of the padding on the rolls.
